In short, not really. The transmissions may be a weak point in the X drive train but not to an extreme extent.

I think the tranny problems with the X are like the tranny problems with the earlier Dodge Rams. You heard about a lot of failures, and how crappy they are, but with regular service, they seem to live an average to long life. Change the fluid every 50k miles, and drive it until it dies.

I see most are talking about the hydro transmissions. What's the concensus on the manual transmissions?

I've used Redline in my M5 for years w/o an issue. I change it just as frequently as the auto's I have. For the cost, $20-$30 worth of fluid every 3 or 4 years is far cheaper than $5000 every 7 or 8 years when the tranny fails. Ever since I started buying BMW's in 99, I've never experienced a failed, notchy or hard shifting tranny, and I by no means have any plans to either.

I read about transmissions going bad on the x's before I bought mine... so tell me people lets get honest here, which transmissions go bad?
1. The 5 speed auto? 2. The 6 speed auto? 3. The 5 speed manual?

Thanks guys for all the info. Sounds like service intervals are the key. Any of you unhappy with the 6 speed auto?

My Audi A4 manual trans hit 125,000 miles and driven hard after I got my new turbo on it and it still ticking (no slippage symptoms yet). BTW, all v8 X5 come with auto. |
